JAMES r. Eocene, orcnnnramowiv, PENNSYLVANIA;

TocZZ whom may concern:

Be it known that I, JAMES P.'Hoornn, a

citizen of the United States, residing at Gerinantown, in the county of Philadelphia,

.State, of Pennsylvania, have invented a new and useful Automatic Bobbin- /Vinding Mechanism, of which the following is a specification.

My invention relates to improvements in automatic bobbin winding.

The object is to provide improved means for automatically feeding the bobbin to the winding mechanism for winding the thread. thereon. fox-catching the thread to be wound on the next bobbin and severing the thread from the wound bobbin and deliveringthe \vound bobbin.

Referring to the drawings, which'illustrate by way of example a preferred means for effecting my inventionFigure ,1 is a plan view of a double headed machine. Fig; 2 is a section on line 22 of Fig. 1. Fig. 3 is a front elevation. Fig. 4 is a plan of the righthand carriage and cam for actuating the guide rod. Fig. is a front elevation of the carriage.

simultaneously. The bobbins are delivered from magazines to suitable driving head and tail stocks, which are operated to'release the bobbins when the some have been wound with the iequired amount of thread. The driving heads .47. see Figs. 8, l5-and 20, are mounted on the driving spindle 43. Spindle 43 is provided with 40. 40 meshes with 39 on'shaft 38. Shaft 38 is provided with gear 37 which meshes with gear 35 on the main driving shaft 30.

The specific construction of a head 47 is illustrated in Fig. 20.. On each end of spindle 43 is mounted a'driving collar 44. Collar 44 has a pin 45 which engages the projection 46in the tinge of head 47. Head 47 is provided with lugs 48 for coiipcrating with recess es in the end of the bobbin 49 for driving" the bobbin. When the bobbin 49 becomes filled with the thread,

the periphery of the thread engages the head 50 on. the rod 51, controlled by spring and actuates the pusher 53, justably secured to the rod 51, see Figs. 7 and 22. The pusher 53 when actuated en: gages the hanging lever 54 pivotally mounted at on the carriage 56 which is slidably mounted on the guide rods 57 and 58. The lower end of lever 54 has a horizontal projection 59 which slides through a support 60 connected with the carriage ed when pushed forward in the direction of the arrow, see Fig. 7, to engage in a recess or opening 61 in the actuated rod 32. The actuation of the lever 54 by the push member 53 is against the counterweight 62 which normally keeps the extension 59 out of engagement with the recess or opening 6] of rod 32. When the projection .59 is engage-d. in the recess 61 of rod 32 it is carried 31. hen extension 59 of lever 54 is pushed into engagement with the. recess of rod 32 and is then moved by said rod, lever 54 engages with rod 124 and is prevented from:

disengaging from lever 32. until it has made a complete reciprocation. The springs 120 serve normally to maintain the carriages in initial position and to take up any play.

Secured to the carriage 56 is the rod'63 and to the end of rod 63 is pivotally conhosted the lever 64 which is connected to tlic ffix'ed pivot 65 and is provided at ltfl gear 42 meshing with. one set of teeth on idler 41. Idler 41 has another set of teeth meshing with idler gear which is ad 56 and is adaptbackward and forward due to'the reciproeating motion of bar 32 actuated by the cam lower end with a slot 66 in which operates the pin 67, which pin 67 is adjustably secured in the slot 68 to the bar 69, see Figs. 5 and 14. The bar 69 slides between a raised guide 70 and the roller 71. Rigidly secured to bar 69 is the block 72, and to block 72 is adjl'lstably secured the rod 73 which is slidably mounted on the stationary framework and carries the tail-stock 74. This 'tail-stock 74 carries the spring actuated'center 75, see Figs. 14 and 15. The reciprocation of the carriage causes the reciprocation of the tail-stock and consequently the releasing of the bobbin.

supports the latch lever 77 pivoted at 78,

I 4 83 project.

Secured to carriage 56 is the arm '76 which see Figs. 8 and 13. l/Vhile the bobbin is beingreleased it is desirable to remove the thread from the guide 36 which is accomplished through themoving of the carriage andthe arm 76.

The frame79 is pivotally mounted on the rod 80 secured to the stationary framework and also on the reciprocating thread 'uide rod 81, see Fig. 11., On this frame F9 is secured the plate 82. plate 82 project the pins 83, there being two in number. Adjacent the plate 82 is the plate 84 provided with part horizontal and part inclined slots 85 into which the pins Plate 84 is provided with the pins 86which project into the vertical slots -87. of the plate 88. Secured to plate 88 is the boss 89, see Fig. 12, to which is secured the rod 90. Rod 90 projects into the slot 91 of lever latch 77. The rod 90 also projects into an aperture in the bracket 92 which forms the supporting connection between ,arm 76 and the lever latch 77, see Fig. 8. It follows therefore that when the carriage moves in the direction of the arrow, Fig. 8, the bracket 92 which is in engagement with the pin 90 will carry the pin and consequently move plate 88 in the T-slot in member 7 9.- The movement of plate 88 to the left also carries the plate 84 to the left due to the engagement of the pins 86 in slots '87. .The movement of plate 84 causes it to rise due to the engagement of the pins 83 in the slots 85. Upon the elevation of the plate 84 its upper margin engages the thread and lifts the same out of the guide 36 which is continually reciprocating. The projection '93 on plate 84 serves to carry the thread over-into a plane of the face of the driving head and the cutting knives hereinafter to be described. When the several 'platesmesume the original position due to the complete reciprocation of the carria e 56 the guide 36 will catch the threa in the slot 94 and will resume winding :1 new bobbin.

- Arm 96 is secured to the stationary framework 95 and pivotally supports at its up per end the bobbin magazine 97. The plate On the underside of 99 is pivotally secured at 98 to magazine 97.

I Secured tothe member 96 is the rod 100 zine is in the normal position, but when the magazine is thrown into the outer or delivery position arm 102 permits the bobbin formerly resting thereon to drop to the position shown in Fig. 23, to rest upon the bent extension 103 connected with plate 99. Secured also to bar 95 is the frame 104 upon which is fulcrumed at 105. the bell-crank lever 106. One arm of bell lever 106 is connected by the connecting rod 107 with the magazine 97 near its lower end. Secured to the carriage 56 are the pins 108 and 109. These pins are adapted to actuate the other arm 111 of bell-crank 106 at the proper moment, that is toward the end of its movement in one direction to push the magazine out to deliver a bobbin. Below the magazine and supported thereby is the cradle 110 which catches the bobbin as the same moves olf the wire support 103 as the magazine is withdrawn away from the same. It is to be, noted that this cradle mgves through an arc intersecting the driving center of the head. The extension 111 of lever 106 is maintained in its difierent positions of actuation by'a spring detent 112. Upon the first outward movement of the magazine. the bobbin which has fallen into the cradle at a previous operation is carried to the position corresponding to the center of the head,whereupon the tail-stock is caused to engage the bobbin and press it sufiiciently against the head to slightly inclined position as indicated. in

Fig. 21. The thread which has been carried over by theprojection 93 will lie upon the projections 48 of the head 47 and will be held there between the head of the new bobbin and the driving head, due to the pressure of the spring ofthe tail-stock. When the head 47 is pushed into the operative position as shown in Fig. 15, the shoulder 46 is pushed clear of the guide 114 and into locking engagement with pin 45, so that the head 47 is locked to rotate with shaft 43.

For cutting the threadI have provided the following mechanism: The plates 115 are secured to the stationary frameworln as shown in Fig. 15, and form a guide and support for the knife 116 and a guide for knife element 117. The knife element 117 is suitably supported on one of the platesllfi andpin engagement, see Fig. 16, and is actuated by the engagement with pin 118 and a projection of the tail-stock 74, as indicated in Fig. 15, forced to straddle the knife 116 and cut the thread 119 therebetween. *This cutting operation happens almost simultaneously with the start of the winding of the new bobbin.

The pin 121 projects from the main frame of the device, see Figs. 8, 9, 10, 11, 12 and 13. When the carriage 56 carries bracket 92 in the direction of the arrow, Fig- 8, "it causes the lever latch 77 to engage with pin 121 and is thereby operated to move the thread guiding mechanism away from the surface of the winding bobbin and out of the path of travel of the bobbin magazine, which is held in said, position during the reciprocation of the carriage.
